The Long Short-Term Memory network or LSTM is a recurrent neural network that can learn and forecast long sequences. A benefit of LSTMs in addition to learning long sequences is that they can learn to make a one-shot multi-step forecast which may be useful for time series forecasting. A difficulty with LSTMs is that they can be tricky to configure and it

Due to the higher stochasticity of ﬁnancial time series, we will build up two models in LSTM and compare their performances: one single Layer LSTM memory model, and one Stacked-LSTM model. We expected the Stacked-LSTM model can capture more stochasticity within the stock market due to its more complex structure.and long-term dependencies forecasting horizon. Hence, we applied the long short-term memory (LSTM) [22,23], which is a special type of recurrent neural network (RNN) architecture [24], to solve the STLF problem. The vanishing gradient point is a problem for RNNs in handling time series; LSTM

Answer (1 of 4): Generally, in time series, you have uncertainty about future values. Ask yourself: in this series, is the uncertainty stochastic or epistemic kind? If the series has truly random behavior, use a probabilistic model. ARIMA-type models have implicit Gaussian assumptions and are a ...The procedure for building this forecasting framework is as follows: First, the denoised time series is generated via discrete wavelet transform using the Haar wavelet; second, the deep daily features are extracted via SAEs in an unsupervised manner; third, long-short term memory is used to generate the one-step-ahead output in a supervised manner.
